The Tennessee Valley Authority has released a draft version of a plan that evaluates its options to meet its power generation needs during the next 20 years, and it is accepting public comments.

Under development since early 2018, the draft of the Integrated Resource Plan was released for public review on Friday.

The Integrated Resource Plan is a power planning roadmap, TVA said in a press release Wednesday. It examines a variety of economic, regulatory, and market-driven scenarios and strategies—both within and outside TVA’s control—to help the public utility respond to changing energy demands while continuing to provide reliable power at the lowest possible cost, the press release said.

“The 2019 IRP emphasizes the importance of flexibility in our generation in response to the changing energy marketplace,” said Laura Campbell, TVA vice president of enterprise planning. “TVA looked at a wide range of possible futures, and flexibility is important in every case to ensure a reliable power supply.” [Read more…]

The coal-burning Bull Run Fossil Plant in Claxton and Paradise Fossil Plant Unit 3 in Kentucky are not economical to operate, and retiring them will offer a savings of about $320 million and avoid more than $1 billion in capital costs, the Tennessee Valley Authority said Thursday.

The TVA Board of Directors voted 6-1 to close Paradise Unit 3 and unanimously agreed to close Bull Run during a meeting in Chattanooga on Thursday. Paradise could close by December 2020, and Bull Run is expected to close by December 2023.

The Bull Run and Paradise closures will be the first 1,700 megawatts of coal plant retirements of the 2,600 megawatts that could be retired through 2033 under a 2015 integrated resource plan, TVA President and Chief Executive Officer Bill Johnson told the board.

An assessment by the Tennessee Valley Authority will evaluate its power generators, including the coal-burning Bull Run Fossil Plant in Claxton, and determine whether the plants will be needed in the future, a spokesperson said Monday.

The focus of the assessment, which could take three to six months, will be on plants that are the least efficient, least cost-effective, and expected to have the highest future costs, TVA spokesperson Scott Brooks said. Plants that fit into that category are the Bull Run Fossil Plant, the one remaining unit (Unit 3) at the Paradise Fossil Plant in western Kentucky near Drakesboro, and combustion turbines (gas turbines), Brooks said. The assessment will look at whether TVA needs Bull Run or Paradise or combustion turbines in the future.

No decisions have been made yet, Brooks said.

He said TVA is assessing its entire generating asset base, including coal, nuclear, natural gas, and hydropower. The public utility is always evaluating its energy mix and making decisions, Brooks said. TVA President and Chief Executive Officer Bill Johnson cited a “mismatch” between energy supply and customer demand, according to S&P Global, which attended a quarterly TVA board meeting in Knoxville on Wednesday.

The results of the assessment will be provided to the TVA board of directors. It’s not clear yet if the assessment will include a recommendation to the board, but the board could make a decision based on the assessment. [Read more…]

TVA: Kingston Ash Recovery Project follows new EPA guidelines

U.S. Environmental Protection Agency guidelines for coal combustion products released on Friday are consistent with work the Tennessee Valley Authority has already done at the Kingston recovery project, the public utility said in a press release.

“TVA is already making substantial changes in the way we work with coal combustion products, including coal ash and gypsum, said TVA President and Chief Executive Officer Bill Johnson. “This included committing an estimated $2 billion to convert all our coal fleet impoundments from wet to dry storage. While recognizing the significant potential for beneficial reuse of ash and other products, we agree it needs to be handled and stored safely.”

The project area surrounding the Kingston Fossil Plant near Harriman is in the final restoration stage following the coal ash spill in December 2008. It was the largest ash spill in U.S. history. [Read more…]

TVA: Kingston Ash Recovery Project nears completion

The Tennessee Valley Authority is in the final stages of the Kingston recovery project. The public utility says it’s fulfilling a promise to restore the area surrounding the Kingston Fossil Plant near Harriman following the coal ash spill in December 2008, the largest ash spill in U.S. history.

A major milestone was reached in early December, with the completion of the cover for a 240-acre permanent ash retention landfill. The new landfill, which has been fortified with an underground earthquake-resistant wall anchored in bedrock, is covered by a flexible-membrane liner and geo-composite fabric, two feet of clay, topsoil, and grass.

“We all know this incident shouldn’t have happened,” said TVA President and Chief Executive Officer Bill Johnson, who visited the recovery site on December 17. “But we have learned from it and we are fulfilling our commitment to making it right.”

TVA says it’s also keeping its promise by returning the Emory River and surrounding waterways to pre-spill conditions, reforesting and adding vegetation to surrounding land, stabilizing shorelines, and adding wetlands and other wildlife habitats. TVA has opened Lakeshore Park, which features 32 acres of walking trails, fishing piers, a boat ramp, and docks. [Read more…]

The Tennessee Valley Authority board of directors recently approved a plan that will retire eight coal units at three plants with more than 3,000 megawatts of combined generating capacity.

The retirements affect all five coal units at the Colbert Fossil Plant in Tuscumbia, Ala.; one of two operating coal units at Widows Creek Fossil Plant in Stevenson, Ala., and two of three coal units at the Paradise Fossil Plant near Central City, Ky. Paradise Unit 3, one of TVA’s largest coal units, will continue to operate.

A number of these units were already idled or scheduled for idling and/or retirement based on an agreement with the Environmental Protection Agency, TVA said in a press release. [Read more…]

TVA board approves smaller budget, 1.5 percent rate increase

KNOXVILLE—The Tennessee Valley Authority board of directors approved a $10.5 billion fiscal year 2014 budget at its meeting Thursday and a 1.5 percent retail rate increase—TVA’s first increase in two years.

The public utility said the rate increase is less than the economy’s modest growth in inflation since the last increase in 2011, and it will add about $1.50 to the monthly power bill of a residential consumer using 1,000 kilowatt-hours of electricity. [Read more…]

KNOXVILLE—The Tennessee Valley Authority reported Monday that electricity sales were lower in the third quarter of fiscal year 2013 than for the prior period due largely to mild temperatures, while heavy rainfall boosted low-cost hydroelectric generation.

“Both sales and revenues were down in the third quarter. This was offset largely by our efforts to reduce operating costs,” TVA President and Chief Executive Officer Bill Johnson said. “We are focused on making sure TVA lives within our means to continue to keep rates low for our customers and the people of the Tennessee Valley.” [Read more…]

TVA sales flat in first quarter 2013, revenues consistent with prior year

KNOXVILLE—The Tennessee Valley Authority reported Tuesday that electricity sales were relatively flat in the first quarter of fiscal year 2013, total revenues were consistent with the prior year, and net income was down.

“TVA’s total operating revenues remain on plan,” new President and Chief Executive Officer Bill Johnson said. “We continue to drive performance and process improvements in order to provide cleaner and low-cost energy to our customers.”

Higher off-system sales as a result of excess generation and closer-to-normal temperatures for the period, compared with even warmer weather a year ago, contributed to a slight 0.2 percent increase in total electricity sales, TVA said in its quarterly filing to the U.S. Securities and Exchange Commission for the three months ended Dec. 31, 2012.
